IMPROVEMENT IN MACHINES FOR MARKING BOOT AND'SHOE FRONTS.

Specification forming part of Letters Patent No. 209,741, dated November'5, 1878 application led October 7, 1878.

Figure 1 denotes a top-view, Fig. 2 an end elevation, Fig. 3 an under-side view, Fig. 4 a front elevation, and Fig. 5 a transverse section, of it.

My machine, in the main, is a combination consisting of a base-plate, a marker and its operative carrier, and a series of gages, and mechanism for simultaneously moving or adjustin g such gages,there being also to the machine an index or pointerto indicate on a scale the extent of movements of the gages for different sizes of boot-fronts to be marked or stamped, as hereinafter explained.

Previous to crimping the front of a boot-upper it has been customary to fold it on its medial longitudinal line, so as to crease or mark it in a manner to enable it to be properly adjusted in the crimping-machine. My present machine is to mark or indent the boot-front along its middle lengthwise, and also trans-A versely directly between its opposite heelpoints, its gages being provided with mechanism for accurately adjusting them for the different sizes of boot-fronts. Each of such sizes usually varies from the next size to it, as followsthat is to say, in length one-quarter of an inch, in extreme width one-eighth of an inch, and inwidth of leg one-sixteenth of an inch. Therefore I have in my machine mechanism for correspondingly moving its gages the requisite distances for each size of bootfront, and I also have the sizes indicated by a scale and index-pointer, which and the gages are operated or moved simultaneously, as hereinafter described.

In the drawings, A denotes the bed-plate or .base of the machine, it being hollow or recessed and slotted to receive the gages and their operative mechanism. To operate with this bed is a marker, B, which is composed of a long cured to its carrier G by clamp-screws c c, go-

ing through slots d d in the blade a, such serving to admit of the marker being moved or adjusted lengthwise of it, as circumstances lmayrequire, to bring the blade b into its proper position for marking as a size may require. r

The marker-carrier O, formed as shown, is pivoted to short standards c c, erected on the base-plate. When the said base-plate is made of wood there may be fixed to it, along its middle, a strip of metal, j', to support the bootfront under a blow of the marker. Further more, there is combined with the base-plate a series of gages, D E F, which, formed as represented, have their shanks extending through and fixed in carriers G H I, that extend up through slots g h t' in the plate, all being arranged as shown.

Transversely under the middle of the baseplate are two screw-shafts, K L, which are supported in suitable bearings, as shown at k Z m n, the shorter of such shafts-viz., L-being disposed at right angles with the longer of them, there being fixed on the latter shaft a bevel-gear, o, to engage with a smaller bevelgear, p, fixed on the shorter shaft. The pitch radius of the larger gear is double that of the smaller one. Furthermore, the longer shaft is provided with two screws, q r, the first being single-threaded and the second doublethreaded,77 in order that during each revolution of the shaft the carrier H may be moved twice the distance ofthecarrer G, whichis connected to a curved arm, s, that screws on the screw q, There is xed on the outer end of the shaft K a milled head, t, to enable it to be turned by hand.

The shaft L has a double-threaded screw, u, made upon it to work in or screw through the gagecarrier I, and there extends from such can ted lines as applied to the gages. .After it may have been suitably arranged against them the marker-carrier should be turned down smartly7 so as to carry and force the lower edge of the marker into Contact with the boot-front in a manner to marl; or indentit along its middle and otherwise, as hereinbefore explained.

I claim- 1. The combination of the base-plate and the marker and its operative carrier with the series of gages provided with mechanism for adjusting them for different sizes of boot-fronts to be marked, all being arranged to operate substantially as set forth.

2. The combination ot' the base-plate and GEORGE C. WILSON.
